Frequently Asked Questions
What is the operating voltage range of the SN74LVC573APWT?
The SN74LVC573APWT operates from a supply voltage (VCC) of 1.65V to 3.6V. Its inputs are 5V tolerant, making it suitable for interfacing between 3.3V logic systems and legacy 5V devices without additional level-shifting components.
What package does the SN74LVC573APWT use and what are its dimensions?
The SN74LVC573APWT comes in a 20-pin TSSOP package (JESD-30 code R-PDSO-G20), a thin small outline package with 0.65mm pitch. This compact form factor is well suited for high-density PCB designs in embedded and portable applications.
What is the difference between the SN74LVC573APWT and SN74LVC573ADWR?
Both devices are functionally identical octal D-type latches from TI's LVC family with 3-state outputs. The SN74LVC573APWT is in a 20-pin TSSOP (PW) tape-and-reel package, while the SN74LVC573ADWR uses a 20-pin SOIC (DW) package. Choose based on your PCB footprint and assembly requirements.
Can the SN74LVC573APWT be used as a replacement for the 74HC573 or 74HCT573?
Yes, in many designs the SN74LVC573APWT can replace 74HC573 or 74HCT573 devices when operating at 3.3V. However, note that the LVC version has a lower maximum supply voltage (3.6V vs 5V for HC/HCT). Verify signal levels and timing parameters against your specific design requirements before substitution.
